**Reigning champion Roger Federer booked a US Open quarter-final clash against Robin Soderling with a 7-5 6-2 6-2 win over Spaniard Tommy Robredo.**The world number one broke Robredo in the 11th game to clinch a tight first set before breaking twice more in a far more comfortable second.
An aggressive Federer wrapped up victory in the third set with an ace.
Soderling became the first man into the quarters when Nikolay Davydenko retired in the third set of their match.
The Swede, who lost to Federer in the French Open final, was 7-5 3-6 6-2 ahead when the Russian quit.
“He’s got a big game and we had the final of the French Open - one of the most important matches of my career - so it’s nice to play him again,” Federer said of his forthcoming clash.

Robin Soderling
“He has got some great shots and is strong off the baseline.”
Soderling was in confident mood ahead of the re-match.
“I have improved my game in every aspect and I just need to do it in majors,” said Soderling.
“I have been beating good players and that has boosted my confidence. I think I have a chance to do well on hard courts.”
A disappointed Davydenko, who was seeded eighth, seemed unsure as to what caused his pain.
“Just some muscle problem, like groin muscle maybe,” he said.

"In the middle of second set I felt something painful in the muscle, and every point I have more and more pain.
"I called physio as I was thinking, ‘What is wrong’ I really don’t know if it was a big injury or small injury. And physios also cannot tell me anything.
“I need some MRI scan to check my muscle.”
